Vectors and Rotators • Vector: Float X Y Z • Network Replication: 16bit int (-32768-32767) • Rotator: Integer Pitch Yaw Roll (16bit U-Sig) • Network Replication: 8bit ints (>>8) • Unrealscript uses radians • 2Pie = 360 Degrees = 65535 • Degrees = Rad * 180/Pie • Radians = Deg / 180 * Pie • UUnits = Rad* 32767.5 / Pie • Radians = Uunits / 32767.5 * Pie

Vector from Rotator Var rotator myRot; Var vector myVect; myRot = rot(32767.5, 0,0) // Upside down myVect = vector(myRot) // Or adding magnitude myVect = 100* vector(myRot)

Vector Size Var vector A; Var float B; A = vect(0, 20, 0); // Magnitude of vector A B = VSize(A);

Normalising Vectors Var vector myVect; Var vector myNorm; myVect = (21345,1234,4343); myNorm = Normal(myVect);

Dot Products • These are used for the angle between two vectors Var vector A, B; Var float angle; A = vector(10,1234,1234); B = vector(0,0,324); Angle = Normal(A) dot Normal(B);

Modifying Rotators in existing Classes • After creating your rotation, you MUST use SetRotation(); • This is the same as movement, using SetLocation(); or Move(); etc • All defined in Actor.uc

Linked Lists • These are your replacement for dynamic arrays, which are not available in UnrealScript This is a 2 part solution, we have a handler, and an Array Object Class ArrayContainer extends Actor; varArrayObject ObjectNo1; Class ArrayObject extends Object; VarArrayObjectNextObject;

Enumerating Objects VarArrayObject Element; For (Element= ObjectNo1; Element!=none; Element= ObjectNo1.Next) { // Do something }

Adding to the Array Class Object: TempElement = New (none) class‘ArrayObject’; Actor Object: TempElement = Spawn(class’ArrayObject’) Depends on which type of object your list is made of

Adding to the Front = Easy TempElement.next = ObjectNo1; ObjectNo1 = TempElement;

Adding to the back = Almost as Easy VarArrayObject Element; Element= ObjectNo1 While(Element.Next != none) Element= ObjectNo1.Next; Element.Next = TempElement; TempElement.next= None; // Not really needed!

Adding to the middle = hardest VarArrayObject Element; For (Element= ObjectNo1; Element!=none; Element= ObjectNo1.Next) { // Check if this is the element we want to insert after break; // Stop at this point } tempElement.Next = Element.Next; Element.Next = tempElement; // Done!

Removing Objects VarArrayObjectdoomedObj; For (Element= ObjectNo1; Element!=none; Element= ObjectNo1.Next) { if (Element.Next == doomedObj) { Element.Next= doomedObj.Next; return true; } } Return false;

Game Types and Limitations Deathmatch Games • All you need are weapons, PlayerStarts and a good navigation network • This encompasses Team DM, Last Man Standing, etc • Anything that has the only real goal of Kill or be Killed • xGame.xDeathMatch, xGame.TeamGame

CTF (Capture The Flag) • Two teams Only supported • One flag per team (multiples will fail) • xGame.xCFTGame • You must have an xBlueFlagBase and xRedFlagBase. • Symmetry / A-Symmetry is required as there is no team-swap mid game

Double Domination • Teams must ‘control’ two points on a map for 10 seconds to score a point • Level needs to have two points or more • xDomPointAxDomPointB, etc • You can use xMonitor->xDOMMonitorA / B to create monitors which show who is controlling the area

Bombing Run • This game type requires 3 objects • xBombSpawn actor • Two xBombDelivery actors • With Team->Team set to 0 and 1

Onslaught = Sweet • Power Cores • Vehicles • Teleport Pads • Power Nodes • Link Setup Must be exported to UnrealEd from In-Game

Linking Power Nodes and Power Cores • Start your ONS map • Press esc, select the Map button • Click on Link Designer • Create your links then click on the ‘Export to UnrealEd button. • This copies the info into the cut-paste ram. • Right click in the level editor and select paste. • An eagle head will appear labelled ONSPowerLinkOfficialSetup

Assault = Difficult • Set Up Objectives • Player Spawn Management • Intro and Ending Scenes

Objectives • TriggeredObjective • HoldObjective • DestroyableObjective • ProximityObjective

PlayerSpawnManagers • You need two for each objective • Attackers • Defenders • Team Numbers are used on the PlayerSpawnPoints to identify their associated Manger and thus Objective.

The End
